--- Comment #1 from Richard Biener <rguenth at gcc dot gnu.org> ---
or for better latency compress with full mask, in parallel compute the lane to
extract and then shift/shuffle things to get the lane in zero position. I also
see compress isn't available for HImode or QImode elements.
To recap, we have operations under a mask and we'd like to extract the
last operation result from a vector.
If we can get a mask with just the last bit set we can use compress.
